• Energy savings of up to 30% can be achieved by re-using heat that is wasted in the roof space.

• The open bladed low velocity fans typically use only 75 watts of power (each), but move a massive amount of air at low speed - hence they increase the working level temperature without causing undue draughts.

• They are fitted as standard with variable speed controls - can be operated at high speed in summer to provide cooling.

• In recognition of the reduction in carbon emissions achieved, installations can in many instances qualify for a low interest rate loan from The Carbon Trust (for qualifying companies – click for full details). http://www.carbontrust.co.uk/
